TEMPORARY BINDER.

To allwhom it may co'nerf/L:

Be it known that I,- GILBERT C. SHEP- HERB, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Temporary Binders, of which the following is a specification.

The object of my invention is to rovide a binder of this class in which the eaves or pages are held firmly and securely, and from which said pages may be removed without difiiculty or delay, and replaced as desired. This object is accomplished by means hereinafter described..

For a more particular description of certain embodiments of my invention, reference is to be had to the accom anying drawings forming a part hereof, in wlhich- Figure 1 is a'plan view oi a binder provided with my improvement. Fig. 2 is a longitudinal section of thesame. Fig. 3 is a sectional view showing the manner in which the sheets are held in place and the pages flexed, irrelevant parts being omitted. Fig. 4 is a perspective view of a slightly modified form of capv used on the clamp of the binder. Figs. 5 and 6, are detailed views showing different forms of housing for the binder fingers. Figs. 7 and 8 are side plan and elevations respectively, of a peculiar type of binder fingers.

Throughout the various views of the drawings, similar reference characters designate' similar parts.

My improved binder comprises'a back 1 with angle metal ca s 2 riveted or otherwise secured to each en Oneof these caps is recessed at 3 for a purpose which will a pear below and both extend and run paral el to guides .4, which are also composed o1 angle metal, and are supported on the back 1 by means of pillars 5. The guides 4 may be given any suitable shape, but are preferably provided with flanges 6, as clearly shown in igs. 1 and 2, so that the caps 7 at each end of the clamps 8 may freely slide on the guides 4, and yet always be parallel to each other in all directions which these clamps 8 occupy.

The clam s 8 are preferably madeof sheet metal bent i o the form shown in Fig. 3, and are provided at each end with the flanged caps 7 which iir'eriveted or otherwise ixedly secured to said clamps. The Clamps 8 are brought together, or separated by means of Specification of Letters Patent'.

toggle levers '9, which are connected with said clamps 8 by means of studs 10, and at the otherends these toggles 9 are connected with a slide 11 by means ofstud's 12, which studs 12 are placed near each end of the slide 11. To properly hold the toggles 9 in place the studs A1() hold the toggles in the brackets 13, which may or may not be dis- The slide 11 moves only in the direction of its length and is secured and held so as to move only-` in this. way, by means of guides 14 and 15, which are secured to pillars 16 and 17 respectively, which pillars are secured to the back 1. Ex-

tend-ing through the length cin the binder is the longitudinally disposed angle plate` 18 which is securedby rivets 1Q to the back 1 a little to one side of its longitudinal center to brace the curved back throughout its length. The slide 11 has brachcts 3() on each side of the nut 20, which engag s a sai-ew 21, whichI screw is journaled in block 22 at its inner end, which block is riveted to the bac-.k 1, and intermediate of its end this srcw 21 is journaled in the plate 23. A collar 24 in.-` tegral with the screw 21 and a shoulder 2.1 which bears against the block 22 prevent the screw 21 froinhaving anjl longitudinal 'movenient, so that when this screw is rotated thc nut 20 is niovcd in thc dire-ition of the axis of the sfizrew 21 which is parallel toit-he dirption of the axis of the slide 11, and the screw 21,is made square or noni-ircular at its outer end, so that this screw can be turned bj.' a .key 26, which passes through the recess 3.' Froni this it is obvious that by jurnilug the key 26 when in-the position shiwpo ini-"g: .1 the slide 11 is moved in the diroetimi of it. length and the toggle arms 9 act to either draw together or separatel thc clamps fs". The clamps 8 are provided v, ith housings 27, from which and into which fingers 255 extend'.- As both the housings and binding tingersare` somewhat complex, l- `will 'describe both separately and at some length.

The 'binding fingers mal,T .be o' the `conventional form as shown in Figs. 5 and 6, in which each binding finger comprises a bar 28a, which is pivotally mounted in a housing, or it may comprise a chain as shown inv Figs. 1, 3, 8 and 7,"which chaininay be. varied as desired., 'In Figs. 3, 5, and 6, the housing is shown' as a hollow 'metal lugr `with a pivot running parallel to the longitudinal aXis of the binder, and is pivoted to the chain 28 against the n Veo ized. In the structure shown in binding pin, this housing being so shaped l a greater portion ofthe surface ofthe page 29 that thepage are flexed through the line of l to be uti perfora ions and clamped below this line.

In 3 1s shown a chain binding finger in whit'. i tv-:o 'roars of linlis are pivotallj' connected to forni a chain finger 28h, and in Firs. 8 and 7 is shown a modification in which three rows of links are riveted to getl'isr in a manner somewhat similar to an ordin. 2! sprocket chain to form. a cl'iain binding finger 28". Because of tin` peculiar constitutions of the chain shown in iiigst; and 7 it isfobvions that the joints are staggered between the intermediate roei; of linlrs and the outside rows of' links on ea-:f/h side thereof, so that theA thain is ..zontinuous and without a break extending through one dgtor side finan-fof, under all eonilitionsi y ndent to itsuse in thebinder, whiic'hoi'ding the slni'ets so that the sheets cannot possibi; be caught between the abuttingl rnds o'l' the linlrs under am,T conditions. in either ease, the chain finger is rigid in the direction o f the axes of its rivets and can be flexed in a plane perpfnidicular to the axes of the rivets and pref'eiwi-bij,V is made ras shown in. ifig. 7 with the edges curved at one side onlj'AT indicated at 28d, so that these chain i'inf can be ficxed as indiciu ed in Fig'. l, aridv ii other waff. From this it is apparent that those chains nill hold the pages as rigidlj. rods, because eaah chain can be flexed onliv in one direction, and as the two chains are flexible in opposite directions, and ,com nested by pages or shoots, cach will stifl'cn the other and prevent any undue separation of' the leaves or pages, allowing that portion of the chain that extends beyond the odge of' the binder to be bent over out of the 'u aj' of the cover. The housing 27 inia'i' be made in various forms, as shown in Figs. i, 3, 5, and 6. The housing 27 is closed lon all .sides except two in the form shown in Fig. i at the .free ends of the flexed chains 2S so that these chains vcan pass into and out of said housing as indicated in said f' ure, the link of the l of the housing 27 holds the chain with sufliticnt firmness in each instance.

In Fig. 6 the page 29 inaddition to being flexed at the point '27 is also flexed at the point 27 b', which is in alinementwith the perforations of the page 29.

In Fig. 5, the page 29 is flexed when the binder is open at the point 27 a, and also at the point 27 C, which is just below the binding finger. In this latter construction, the page maye be opened for a greater portion of its length, beyond the binding fingers, which is found to be a great advantage, as it enables Fig. 3 this result is even better obtained by having the pages 29 held by the clamps 8 below the' housings 27, so that-these pages are flexed considerably 'below their perforations. This construction holds the pages 29 securely, and yet permit-s a maximum surface to be utilized, as the sheets 29 bend through the perforations that hold them in piace,features which are of great and material advantage when one considers that hundreds of pages orvsheets are used in each of these temporary binders.

What i claim is: v Y

i In a temporary binder or similar device, a back, binding fingers and clamps connected with said binding fingers, said clamps being soshaped that when the sheets are held in said temporary binder, said fingers will pass through periorations in said sheets, and said sheets will be clamped below said fingers,

and also flexed through the line of perfora- ,tions 2. In a temporary bind-er or similar device,

.binding fingers passing through perforated sheets and clamps fixedly holding said sheets below the perforations, whereby the pages are flexed through the perforations and a temporary binder, the fingers will passv through the perforations in these sheets 'and the said sheets will be clamped below said fingers, and also flexed through the line of perforations when the binder is opened.-

4. In a temporary binder or similar device, means for fixedly holding the edges of sheets, and binding fingers passing through perforations in said. sheets above the point where said sheets are held, whereby the sheets are held fixedly with regard to the binder when the book is open and the sheets are in use.

5. In a temporary binder or similar device, means for clamping and holding perforated sheets, fingers adapted to pass through said perforations, above the part where the sheets are clamped, so that when the book is open the sheets are flexed through said perforations, and means for holding said binding fingers securely in place. p
